BC817-40W/ZLX

Overview

The Nexperia BC817-40W/ZLX is an NPN general-purpose transistor housed in a SOT323 (SC-70) surface-mounted plastic package. It features a collector-emitter voltage of 45 V and a continuous collector current of 500 mA, with a peak pulse current capability of 1 A. The device offers a DC current gain range of 250 to 600 at IC = 100 mA and VCE = 1 V. Total power dissipation is rated at 200 mW at Tamb ≤ 25 °C, extending to 290 mW on specific PCB footprints. Operating junction temperatures reach up to 150 °C.

Feature Summary

High current handling capability for general-purpose switching applications
Three distinct current gain selections available within the series
Compact SOT323 surface-mount package design

Applications

General-purpose switching circuits
Amplification stages

Procurement Notes

Verify the exact ordering suffix against official Nexperia documentation to confirm packaging format and manufacturing site codes. Confirm that the specific revision matches project requirements, as automotive qualification status may vary by suffix. Ensure compatibility with standard reflow soldering profiles defined for the SOT323 package outline.

Selection Notes

Select this component when a compact NPN transistor with moderate voltage ratings and high current gain is required. The BC817-40W variant provides a guaranteed minimum hFE of 250, suitable for efficient base drive requirements. Consider thermal derating curves if operating above 25 °C ambient temperature or utilizing standard PCB footprints.

Part Context

This part belongs to the BC817W series of NPN general-purpose transistors manufactured by Nexperia. The series includes variants with different current gain ranges, such as BC817-16W and BC817-25W. The PNP complement for this family is the BC807W series. All devices share the same SOT323 package dimensions and pinout configuration.

Replacement Considerations

Direct functional substitutes include other BC817-40W parts from different manufacturers adhering to the same electrical specifications and SOT323 footprint. Verify pinout alignment and thermal resistance characteristics before substitution.

FAQ

Is the BC817-40W/ZLX automotive qualified?

No. According to the product data sheet revision history, the BC817W series has been changed to non-automotive qualification. Automotive alternatives are available separately.
